Although the rules state that the Chess Player can't allow the pieces to enter a room they have previously entered, these rules can't trap Gu Mian; only walls that can't be broken can restrain him.
If there were tools to break the walls, Gu Mian would have been like the person who stole light from the wall, creating large holes in every room's walls.
Liu Ruyan looked at what 007 posted in the group chat: "Don't you think it's strange? Group Two was completely dead for a full two minutes before it was Group Three's Chess Player's turn to act."
Each group can only delay time for a maximum of two minutes per round, as the Chess Player has one minute to make a choice and the pieces have one minute to enter the door after it appears.
So even if trying to delay time, a group can only delay for two minutes.
